“…Thermography has great potential for improving the diagnosis of neuropathy (6,14). Dysfunction of a nerve or a local musculoskeletal disorder could be linked with varying temperature patterns, such as local hypothermia or hyperthermia of an extremity (14)(15)(16). The measurement of skin temperature with infrared thermography has been claimed as an objective method to appraise the sequel of regional blocks, such as epidural anesthesia, infraclavicular brachial plexus block, and lumbar sympathetic block (17)(18)(19).…”

Background: Minimally invasive therapies can alleviate pain and improve walking in individuals with persistent foot and ankle pain. Objectives: The current study aimed to define the protracted consequences of tibial nerve blocks with steroids for individuals with persistent foot pain and to investigate the link between the thermography of the plantar foot and the beneficial effect of a tibial nerve block with steroids. Methods: All patients with chronic foot pain (n = 45) in this cohort underwent a block of the tibial nerve in the Department of Pain Therapy of Pain Clinic De Bilt, Utrecht, Netherlands, within November 2019 to April 2020. The thermographic images of patients were taken before and after injection. Results were retrospectively evaluated after 18 months. Results: In this study, 53% of the patients had pain relief at 7 weeks of follow-up with a unilateral or bilateral block of the tibial nerve. An improvement in walking distance was reported by 22% of the patients. Side effects of the tibial nerve block reported at 7 weeks of follow-up increased pain (5%) and the occurrence of leg cramps (5%) among the treated patients. At 18 months, 45% of the successfully treated feet still had benefits. A difference between the big toe’s temperature and the foot’s average temperature of less than -0.9°C on thermography before and after the tibial nerve block can predict a beneficial result of therapy. Conclusions: Tibial nerve block provides a safe, minimally invasive treatment option for almost half of the patients with painful feet in this cohort, and when successful, it can last a long term. Thermographic imaging of the plantar foot can predict only to a small extent the beneficial effect of the tibial nerve block with steroids on foot pain. Tibial nerve block should be considered when custom foot orthoses have been inadequate for pain relief or restricted walking distance.

Differential Screening of Herniated Lumbar Discs Based on Bag of Visual Words Image Classification Using Digital Infrared Thermographic Images

Doctors in primary hospitals can obtain the impression of lumbosacral radiculopathy with a physical exam and need to acquire medical images, such as an expensive MRI, for diagnosis. Then, doctors will perform a foraminal root block to the target root for pain control. However, there was insufficient screening medical image examination for precise L5 and S1 lumbosacral radiculopathy, which is most prevalent in the clinical field. Therefore, to perform differential screening of L5 and S1 lumbosacral radiculopathy, the authors applied digital infrared thermographic images (DITI) to the machine learning (ML) algorithm, which is the bag of visual words method. DITI dataset included data from the healthy population and radiculopathy patients with herniated lumbar discs (HLDs) L4/5 and L5/S1. A total of 842 patients were enrolled and the dataset was split into a 7:3 ratio as the training algorithm and test dataset to evaluate model performance. The average accuracy was 0.72 and 0.67, the average precision was 0.71 and 0.77, the average recall was 0.69 and 0.74, and the F1 score was 0.70 and 0.75 for the training and test datasets. Application of the bag of visual words algorithm to DITI classification will aid in the differential screening of lumbosacral radiculopathy and increase the therapeutic effect of primary pain interventions with economical cost.

“…Schwannomas are most commonly seen in head and neck (25–45%) [ 17 ], mediastinum (20%) [ 18 ], upper extremity (19%) [ 19 ], retroperitoneum (5–10%) [ 20 ], pelvis (<0.5%) [ 21 ], and lower extremities (13.5–17.5%) [ 22 ]. Various studies in the literature reported that schwannomas are common in the anterior and flexor areas of the upper extremities and the posterior aspects of the lower extremities [ 12 , 13 ]. The review of lower extremity schwannoma from 2013 to 2020 is tabulated in [ Table 1 ] [ 10 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ].…”

Introduction: Schwannoma is a benign tumor that arises from the peripheral nerve sheath. It presents as a discrete, often tender, and palpable nodule associated with neurogenic pain or paresthesia when compressed or traumatized. The growth rate is usually slow, and these lesions seldom exceed 2 cm in diameter. Case Report: We report the case of a schwannoma arising from the tibial nerve located in the left popliteal fossa. The patient presented with the left foot pain in the lateral plantar region without any motor deficit. The pre-operative diagnosis was made with magnetic resonance imaging (MRI) scan. He was subjected for neurolysis and excision biopsy of the lesion. The surgical specimen consisted of encapsulated white-yellow mass with irregular contours, measuring 2 × 3 cm. The cut section revealed cystic degenerations with areas of hemorrhage and necrosis. The patient reported symptom free in the post-operative period and during follow-up. Marginal excision appears to be recommended therapy for this tumorous lesion, without any evidence of recurrence during follow-up. Conclusion: A benign nerve sheath tumor of a peripheral nerve could be a possibility for long-standing neuropathic pain in the foot, ankle, and leg, wherein all other possibilities have been ruled out. The meticulous examination of the entire length of the tibial nerve including sciatic nerve by palpation and percussion was helpful in diagnosis which should be confirmed by MRI scan. The excision biopsy remains the gold standard treatment of choice for schwannoma of the peripheral nerve.
